If managed correctly, aquaculture has the potential to greatly increase food supplies of animal origin with less damage to the environment than from land-based animals and birds. By about the year 2035 and using the same area for wheat production, it has been estimated that the wheat yield will need to increase to 20 tonnes/hectare. This will require use of more productive plant varieties and also, if the characteristics are right, it will probably include geneticallymodified (GM) plants and those produced by other technologies. By 2050, there will be an estimated 10 billion people in the world. Focusing on innovation, markets, people, and political leadership is necessary to ensure a food supply that can feed the population, Gordon Conway says. But a new report found that it will be impossible to feed them all without major changes to the global food system. Farming of fish occurred over two millennia ago with the Chinese and Romans. Zero grazing may also be useful. The amount of crop harvests needs to be increased from one a year in most climates. ... but fish farms also tend to catch wild fish to use as feed. Can they do it? It’ll just take some work. Farming has produced problems with pollution and spread of disease to wild fish stock. If the world is to feed 9 billion people in 2050 and successfully navigate ecological tipping points in the face of climate change, solutions such as the above will be needed on a global scale. Andrews, A. H. (2014) Major factors influencing 2050 world food production. Solutions to feeding the world in 2050 essay. Thus, increasing milk yield per cow/goat/sheep, eggs per laying hen/other poultry, larger strong viable litters of pigs/ruminants/other animals, etc., should be the aim. In the case of the waste products in the animal production stage, it can be assisted by producing better balanced diets including lack of excess nutrients, use of dietary ingredients that can be efficiently utilised by the animal, use of additives to further improve digestive efficiency, and also the reduction of stress and disease. Can we produce enough food sustainably? The amount produced will probably need to double to meet the world’s requirements. After land availability and suitable fresh water provision, the ability to reduce, manage and recycle human and animal faecal waste and food waste are major potential limiting factors to food production. Veterinary Practice 46 (10): 34-35. However, we need to remember lessons from the past where wholesale importation of improved breeds to some countries often resulted in disaster because of their inability to cope with the new environment or the diseases present. Substantially more cereal production will be needed to feed livestock in 2050. Fish are very efficient converters of protein eaten into meat protein. It should be possible to integrate some of this with increased storage and distribution of water. The aim is to reduce the replacement rate. Feeding the world in 2050 requires a revolution Paul R. Ehrlich , John Harte Proceedings of the National Academy of Sciences Dec 2015, 112 (48) 14743-14744; DOI: 10.1073/pnas.1519841112 This 22-part plan is how we can feed the world by 2050 We need to slash emissions from agriculture while at the same time feeding billions more people. In the case of herbivores and omnivores, while some are likely to be reared outside, others will spend some or much of their time indoors. It is projected that by 2050, the total world population will reach 9 billion (The World Bank 2016) and with the accompanying growing demand for more food, many challenges need to be addressed concerning food sustainability. As the climate alters, the varieties planted need to be altered in anticipation and in response to such changes. The fish farming industry is well aware of these and is becoming better able to contain and prevent them. These do not necessarily take into account that inputs in the various parts of the food chain can be altered or often there are mitigating factors which may modify GHG or other factors which are not considered as being as important as the calculated footprints. It would be far easier to feed nine billion people by 2050 if more of the crops we grew ended up in human stomachs. It will require increased land use and also increased yields per unit of land. Although many of the fish currently farmed are carnivores, other fish are vegetarians and breeds such as the tilapia are already being raised in South America and Asia. While they require good management, many of the inputs can be recycled and as production is in buildings, they can be multi-storeyed thereby reducing land usage. A greater understanding of the disease also known as infectious bovine keratoconjunctivitis and its prevention would be welcomed by both farmers and vets, The British Mastitis Conference 2020 discussed new developments in tackling mastitis, from the value of selective dry cow therapy at quarter level to the impact of automatic milking systems, Goats are more susceptible to endoparasites than sheep and never form an immunity to the parasites, unlike their ovine counterparts, Despite being able to work in the fresh air with space and applied hygiene, there are still dangers and analysing risk is now the norm. Whilst there has been overfishing of many types of seafish, it is possible that fishing can continue sustainably with suitable regulation and enforcement. The world’s number of total livestock and poultry has risen over 300 percent between 1961 and 2014, due, in large part, to modern feed products and delivery systems. The authors found regions in the world with water supplies that could support this growth. In animals used for meat production, the aim must be to produce more usable food and byproducts from each animal and to do this with maximum efficient feed conversion. Desalination was previously mentioned as one method to increase available fresh water: as almost all water is saline it would seem sensible, where possible, to make use of it. These will continue to provide a core for meat production. However, the type of food provided is open to debate and will probably require change in eating habits in some or most countries. Their suitable recycling or disposal is necessary before any such unit can be considered viable and not proportionately increasing GHGs. Executive Summary – Part 1: How to Feed the World in 2050 e challenge of feeding the world in the year 2050 is fourfold: 1. already in the year 2018, the global food system does not feed its 7.5 billion people properly. The area available for food production will decline because of climate change and housing the increasing global population. Renewed investment, capacity building, improved infrastructures and the introduction of modernised, intensive and integrated production technologies are the main factors spurring higher growth in these countries. CRISP-R technology or gene editing is a way of selectively breeding a plant to get desired traits like higher yields or drought resistance. Productive longevity involves many different factors such as genetics, nutrition, management, environmental adaptation, disease prevention, etc. pp1-11. It is agreed among the experts that our planet will be supporting over 9 billion of us by 2050. The synthesis report of the World Resources Report: Creating a Sustainable Food Future shows that it is possible – but there is no silver bullet. Although not on the diet of many developed countries, the consumption of insects and some other invertebrates is already common. Several species are farmed (such as trout and carp) but to introduce some new species, the public would require education in their eating habits. Ideally, where possible, crops should be grown which can be utilised by man and animals. In fact, the daily greenhouse gas (GHG) emission has recently been suggested for different UK consumer-types (high meat eaters 7.2kg CO2 equivalent; medium meat eaters 5.6; low meat eaters 4.7; fish eaters 3.9; vegetarians 3.8; vegans 2.9) (Scarborough and others, 2014). The United Nations predicts 9.7 billion people will be housed on planet earth by 2050. Authors Timothy A. As our global population continues to rise, some estimates suggest it could reach a whopping 10 billion people by 2050. Future food production will be a challenge. Step Four: Shift Diets. Nearly all of this population increase will occur in developing countries. Pasture management can also ensure maximum utilisation of the pasture without damaging it and ensuring livestock removal when appropriate on a temporary or permanent basis. news; Artificial meat the answer to feeding the world in year 2050. To Feed the World in 2050, We Need to Discuss Agriculture at UN Climate Change Talks 09/10/2013 04:57 pm ET Updated Nov 10, 2013 The relationship between climate change and agriculture is still an area that needs more emphasis at a global level. However, it is likely that, proportionally, global milk and egg consumption will rise faster than most types of meat intake. Simplistically, it would appear that if a food animal is used to continually produce a particular product, then the more of that product produced by the individual the less the drain on resources such as feed, etc. There will be a need for increased water availability and this has been discussed in the previous article (Andrews, 2014). Whilst this may occur, it illustrates the need to produce local technical answers rather than global ones. The projections show that feeding a world population of 9.1 billion people in 2050 would require raising overall food production by some 70 percent between 2005/07 and 2050. Jason Clay, the head of agriculture at WWF US in Washington, once famously calculated that the world’s farmers will need to produce as much food in the next forty years as they produced in the past 8,000 years. The synthesis report of the World Resources Report: Creating a Sustainable Food Future shows that it is possible – but there is no silver bullet. Intensive research and modeling examining the nexus of the food system, economic development, and the environment show why each of the 22 items on the menu is important and quantifies how far each solution can get us. The land will need to be harvested with areas using crops suitable for each environment, and producing maximum yields. No part of this site may be reproduced without permission. Download publication. Farmland is already degraded by existing agriculture, and climate change is putting new pressure on crops and livestock. At present, aquaculture produces about 50 million tonnes annually but the knowledge and expertise is becoming available to increase this with potentially only a limited effect on the natural environment. ... at the Times that showed a range of opinion on what it would take to "feed the world." Farmland is already degraded by existing agriculture, and climate change is putting new pressure on crops and livestock. Suitable water supplies can allow production in otherwise infertile areas. That’s a lot of mouths to feed, ... the world’s population is expected to reach a whopping 9.7 billion by the year 2050. It is also an area where veterinarians can play an active role. Figure 1. Thus, there are many areas where pasture is the most productive or only crop that can be successfully grown. In 2050 we may have almost 10 billion people to feed. Feeding the world in 2050 is possible, even without needing to convert much additional land to agricultural purposes. Registration 3568194 VAT No. By 2050, world food production will need to provide an extra 7.4 trillion calories on top of its 2010 output to meet demand. Meeting this challenge will take all the ingenuity that farmers, companies, conservationists, agricultural experts, ecologists, and others can muster. Co. A s our global population continues to rise, some estimates suggest it could reach a whopping 10 billion people by 2050.To feed that many people, we will need to produce record quantities of food. The scale of the challenge is epic. Feeding the world in 2050. Dr TONY ANDREWS concludes his discussion of the challenges facing food producers in feeding an everexpanding global population, and the role veterinarians will play in achieving sustainability. Feeding The World in 2050- Biobased Solutions for a Growing Population By: Marina Bowie Posted on:01/31/2019 Updated:02/01/2019. While amounts of cereal and other plant crops will need to double, there should still be suitable areas for animal production. Governments will need to take action to ensure everyone gets equal access to food, but through actions like reducing food waste and meat consumption in your own life, you can contribute to a sustainable future for the planet and its growing population, too. George Silva, Michigan State University Extension - December 3, 2018. ... By 2050 the world’s population will likely increase by more than 35 percent. However, in this guide we look at the areas we might focus on (as well as potential solutions and strategies) if we want to increase the probability that the entire world population gets fed in the future. It is agreed among the experts that our planet will be supporting over 9 billion of us by 2050. The extrapolations are based on changes occurring with a country’s increase in gross national production and this has previously been argued as unsustainable on a global basis. ©2021 ‐ Improve International, Alexandra House, Whittingham Drive, Wroughton, Swindon, Wiltshire SN4 0QJ, England. Currently, 40 percent of U.S. corn crop is used for producing ethanol. There are already a lot of mouths to feed on planet Earth but these five solutions may allow us to feed a 10 billion strong population by 2050. There is some potential to increase the harvesting of sea plants for fertiliser and food but the demand for the latter is currently likely to be limited. This will require suitable crop type with minimal and targeted water and fertiliser. Animal production will have to become increasingly efficient and will involve veterinarians undertaking work to ensure this occurs and does not compromise the environment. Using the production of wheat in the United Kingdom as an example, the current average yield per hectare is 8.4 tonnes. Overall, to feed the world in 2050, everyone will need to do their part. Yet, if the world is going to feed an estimated 40 billion livestock and poultry by 2050 in a sustainable manner, further efficiency in animal nutrition will be necessary. The report offers a five-course menu of solutions to ensure we can feed 10 billion people by 2050 without increasing emissions, fueling deforestation or exacerbating poverty. Food and Agricultural Organization (2011) Global Food Losses and Food Waste. The current world population is … Urbanization will continue at an accelerated pace, and about 70 percent of the world’s population will be urban (compared to 49 percent today). As climate change alters the environment in some areas it may be necessary to look at breeds or animal types and species in environmentally similar areas and consider importing them (animals, embryos, semen) as the areas change. What do people think are the obvious/not obvious solutions to 'feeding the world in 2050'. It is suspected, however, that the demand for continuing meat supplies will lead to a compromise over the negative effect of their GHG emissions. Farmland is already degraded by existing agriculture, and climate change is putting new pressure on crops and livestock. Catfish are commonly and easily reared in many parts of the world. Second, a significant portion of the grain is now being utilized for biofuel production such as ethanol and biodiesel. There are various strategies that will reduce their amounts and their effects including intensification, control of dietary constituents, feeding only sufficient, use of compounds to alter ruminant fermentation and digestion, improving efficient production, ensuring good fertility, reducing stress and disease, reducing culling and increasing longevity. While these figures account for the trend to eat more meat and dairy products, these are the most wasteful and least environmental forms of food production. Summary – Feeding The World Population In The Future. How Will We Feed the World in 2050? It is beyond this article to deal with this but with water it is possible to introduce systems which will improve efficiency of water use and collection, improve irrigation methods and ensure that all water is productively used (every drop counts). October 26, 2018 By Leave a Comment. The footprint models used tend to look at all the costs up until it reaches the kitchen. This is considered too optimistic by some who believe that climate change will restrict future yield growth. How to Feed the World by 2050: Biotech Isn't the Answer. The use of these and other species overcomes some of the problems concerning some fish species being used as a protein source for other fishes. Food waste needs to be reduced in less-developed countries by improving logistics and in the developed countries by improving dietary choices, reducing consumption, reducing waste and recycling food materials. Suitable water supplies can allow production in otherwise infertile areas. Solutions Flexibility and well-being for dairy farmers and their cows More about our solutions ... How to feed the world in 2050? ; then the improved utilisation of manure to ensure only sufficient is used on the land to meet crop requirements with minimal soil impaction and run-off. It claims that feeding the world in 2050 without using up our water resources is possible. Almost all salmon eaten these days in Britain and some other European countries has been farmed. Climatic Change 125 (2): 179-192. However, despite this, man is designed as an omnivore and it is most unlikely that all will subscribe to a vegetarian diet. The idea that current food production is enough to feed 10 billion people is … Since the mid 1990s the world wild fish catch has levelled out at about 80 million tonnes annually. By 2050, the global population will reach nearly 10 billion people and global food demand will soar by 56%. Increasing productivity is a more sustainable approach to feeding the global population in 2050. Agroecology mimics nature, replacing the external inputs like chemical fertilizer with knowledge of how a combination of plants, trees, and animals can enhance the productivity of land. To feed that many people, we will need to produce record quantities of food. The world faces the looming challenge of feeding an expanding population that is expected to reach 9 billion by 2050, from just over 7 billion today, while climate change increases uncertainty. THE main problems with animal intensification are the volumes of water used and the waste products produced. To gain more understanding about the problem of feeding the world in 2050, we asked scientists, engineers, economists, architects, and journalists—people at the forefront of research and reporting on this issue—for their ideas and advice. Most animals will need to be intensively kept as this reduces land requirements, although some farms will still produce for niche markets. The cultivation of plants (cereals, rice, protein crops) to produce all food is feasible and it is suggested that it will not greatly increase the carbon or GHG footprint. Large animal Livestock. This is 2.4 times the yields of today and to place this in perspective the current world record wheat yield is 15.6 tonnes per hectare, which was produced in New Zealand in 2010. Many parts of the world have developed animals which are able to cope with their specific local environment. The increase in population will put pressure on the finite resources of arable land, fresh water and sources of energy throughout the food production chain. By 2050 the world’s population will reach 9.1 billion, 34 percent higher than today. Some areas will be best suited to pasture and for use by herbivores. Attitudes to different foods may need to change locally in socio-economic, ethnic and national terms. Only 3% of the world’s water is fresh and of this only 1% is available as liquid. The challenge of producing sufficient food is going to be a massive problem. DEFRA (2010) Household food and drink waste linked to food and drink purchases. Feeding the world in 2050 and beyond – Part 1: Productivity challenges. Feeding the World in 2050 14 CSA News November 2014 H ow can the world feed more than 9 billion people by 2050 in a manner that provides economic op- portunities to alleviate poverty and reduces pres-sure on the environment? key part of the solution to feeding the World in 2050: a source of nutrient-dense animal-source foods that can support normal physical and mental development … The world faces the looming challenge of feeding an expanding population that is expected to reach 9 billion by , from just over 7 billion today, while climate change increases uncertainty. In the future, new technology and attention to breeding may make them more economically viable but without removing inherent characteristics of survival in adverse climates, disease resistance, etc. this from a library global food futures feeding the world in 2050 brian gardner this is the first text to present a scholarly balanced approach to the contentious area of food production and supply up to 2050 offering a readable and well informed account which tackles the consider these other ways that food drives the future of the economy and. Answering it requires a great balancing act of solutions to three needs.
